IMPROVEMENTlN CULTIVATORS.

Specification forming part of Letters Patent No. 8,483, dated November 4, 1851.

To all whom it may concern:

Be it known that I, IsAAo CoNs'rAN'r, of Buffalo Heart Grove, Sangamon County, State of Illinois, have invented a new and useful Machine for Cultivating Corn 5 and I do hereby declare that the following is a full and exact description thereof.

It consists ot' the two horizontal beams A B and C D. Near the back end of the beam A B are tirmly fastened two wrought-iron or steel plowshares, I K and L M. Near the back end of the beam C D are also two corresponding plowshares. Said beams are connected together near the back end by the bow E F, which is fastened to said beams by the screws or bolts a. b. The beams may be farther separated by using the holes c d instead ot' a b. rlhe beams are connected together atthe front end by the bow Gr H, which is fastened by the bolts or screws e f. The front ends of the beams may be farther separated by using the holesz 7L instead of ef. There are also two horizontal plow-beams, P Q. and It S,eonneeted with the handles T U and V W, and fastened at the front end to the bow Gr H by means of a elevis. Into each of these last-mentioned beams is inserted a plowshare, N O and Y Z If it is preferred these shares may be removed and others of the form designated by letter X may be inserted. The last-mentioned beams are designed to work freely at the front end, so that the shares N O and YZ may be brought close together or separated while using the machine, as necessity requires. The design ot' the implement is to have three plowshares work on eaeh side of a row of corn, and so to oonstruct theintermediatejointed plows that they may work elose to the corn and thoroughly eultivate the ground between. the rows. By using this machine the ground is more thoroughly worked and a greater amount of labor performed than by the machines now in use.

What I claim, and desire to secure by Letters Patent, is-

The intermediate jointed plows, in combination with the main cultivating-plows, as described, for enabling the plowman to plow 4nearer to or farther from the rows at will.

ISAAC CONSTANT.
